This initiative, which was successfully tested in Spain, uses new power frequency and voltage control equipment and systems in order to improve the connection between wind farms and electricity transmission grids.
Iberdrola, together with the company Gamesa, national grid operator Red Eléctrica de España (REE) and the Institute of Technological Research (IIT) at Spain’s University of Comillas (Instituto de Investigación Tecnológica de la Universidad de Comillas) have successfully completed the R&D demo project Syserwind. This initiative aims to improve the connection between wind farms and energy transmission grids by creating new power frequency and voltage control systems.

The project was successfully tested at 15 of Iberdrola’s wind facilities in Andalusia (southern Spain), which are equipped with Gamesa wind turbines and possess a combined installed capacity of over 480 megawatts (MW).

These wind farms, connected to three nodes of the 400 kV transmission grid operated by REE, were equipped with systems developed as part of the Syserwind project. This allowed a coordinated effort to control the power generated by the facilities and alter the voltage in the grid. The tests confirmed the technical viability for wind power to take part in the power frequency and voltage control services of the electricity system.

The Syserwind project, led by Iberdrola, was one of six full-scale demo projects carried out under the European Union’s Twenties research program.
